Ask him who he is

He replies: Well technically I'm a character in a game but as I'm also a Representative of Gaby de Wilde I may as well steal/lease his identity. So...I'm Gaby the Wide Creator of this world. (ehm) But are you going to come inside or what? It's freezing out here.

What do you do?

Go inside
Say "no, thanks" and walk to the the next house
Ignore him and walk to the next house
